The most efficient method for reducing the organic content of dilute liquid waste is by aerobic-biological treatment. Basically, the organisms responsible for treatment possess the ability to decompose complex organic compounds and to use the energy so liberated for their bodily functions : reproduction, growth, locomotion and so on. That part of organic matter used to produce energy is converted to the essentially stable end pro ducts of carbon dioxide, water and ammonia, while the remainder is converted to new cells which can be settled and thus removed from the liquid before the waste is discharged to the receiving body water. Oxygen must be supplied continuous ly during the aerobic process. In the field of sewage treatment the Warburg respirometer is used mainly for the measurement of the oxygen uptake of samples. In this experiment the Warburg constant volume respirometer was used to determine the oxygen uptake by the bacteria in the presence of various glucose concentrations. The rate of oxygen uptake by the bacteria was expressed as the respiratoty quotient. The results indicated that the oxygen uptake was proportional to the glucose concentration. The expecting equation of the regression line was Y=7.7 0.12X, where Y : respiratory quotient, microliter. O2 taken up/mg. dry wt. bacterium/hr. X : concentration of glucose, mg/l

Familial Renign Chronic Femphigus(FRCP) is rare, persistent and vesicobullous genodermatoai. Three casee of FRCP with typical clinical and histapathological findings are reported. The first case of FBCP was 27-year-oId man who had recurrent episodes of grou vesicles and rust with miId pruritue at the posterior neck, in both axillae and in inguinal area for 10 years. The second case was 49-year-old woman with skin lesions of recurrent persistent. vesicles, pustules on the erythematous skin, crust and lichenification on the flexural area of extrimeties, axillae, ingumal and neck area for 10 yeara. The third case was 49-year-old male patient who had recurrent pruritic grouped vesicles with crust on the neck and axillary area. In all three patients, skin eruptions usually began and or aggravated in the spring or summer and tend to heal spontaneously in the autumn and winter and showed positive Nikolsky sign. The only one case of the reported three casea had familiaI history of skin lesions similar to FRCP. Histopat,holag;ic finding of biopsy specimens from the vesicular eruption showed auprabasal vesiculation with acantholysis, lacunae and villi formation in all 3 cases.

To a patient suffering from intractable pain due to the terminal state of cervix cancer, 7% phenol-glycerine solution was injected through the L2-L3 interspace. We obtained a good result of pain relief, but motor paralysis developed.

PURPOSE: This study aims to test the validity and criteria-related reliability of the Korean version of the Copenhagen Psyco-social Questionnaire version II (COPSOQ-K) assessing the psychosocial working environment. METHODS: The COPSOQ-K was developed through forward-backward translation techniques, and revision based on feedback from focus groups. Survey data were collected from 311 office workers who worked in one workplace. An internal consistency reliability was estimated by Cronbach's alpha. The impacts of the COPSOQ-K scales on job satisfaction, self-rated health, stress, sleeping troubles, burnout, and sickness absence were analyzed with multiple regression model or multiple logistic regression model, adjusted age and gender using SAS version 9.3. The Pearson correlation coefficients between the COPSOQ-K scales and Korean job stress and its subdomain were identified. RESULTS: Cronbach's alpha of COPSOQ-K scales was adequate or good (0.66~0.87). The major COPSOQ-K scales predict job satisfaction, self-rated health, stress, sleeping troubles burnout, and sickness absence. The major COPSOQ-K scales were correlated with Korean job stress and its subdomain. CONCLUSION: The COPSOQ-K scales have satisfactory reliability and criteria-related validity. The COPSOQ-K scales will be useful for the future studies and practices associated with psychosocial working environment.

Epidermolysis bullosa aimplex is a dominantly inherited syndrome characterized by the dissolution of the basal epidermal cells with mechanical stress. A 23 year-old man developed recurrent bullous eruptions with pain on hands, feet and face since childhood, which healed spontaneously without scarring. Grandmother of his father's side, father, aunt of his father's side and two of his three brothers had suffered similar skin lesions. Light and electron microscopy showed degeneration and bulla formation in the basal cell layer of epidermis and intact basement membrane attached to dermis.

The sign of Leser-Trelat refers to the sudden appearance and rapid increase in size and number of freckles and seborrheic keratoses, It is considered to be a sign of internal malignant tumors, most probable of the gastrointestinal tract. We report a case of adenocarcinoma of the stomach associated with the sign of Leser-Trelat and the literatures were reviewed. This 62-year-old man, over a period of 5 months, developed multiple seborrheic keratoses over his trunk and extremities. He came to our department in August 1981, because of sudden increse in their number and size during the several preceding months. He had never complained of the symptoms of gastrointestinal tract such as gastric pain, vomiting, indigestion, and weight loss. On examination of the skin, hundreds of brown or brown-black, more or less greasy verrucous papules were found almoat exclusively on the extensor aspects of forearms and lower legs. These lesions were variable in size and were consistent clinically with seborrheic keratoses. The findings of both fiberoptic biopsy and upper gastrointestinal tract series of roentgenographic studies were compatible with ulcer and adenocarcinoma of the stomach. Based on our experience, it is again suggested that though seborrheic keratoses are very common in the elderly, the rapid increase in size and number should arouse suspicion of an internal malignancy.

Diiodohydroxyquin introduced by Dillaha et al in 1953, had been the mainstay for the treatment of acrodermatitis enteropathica (A.E.). However, following the report by Moynahan and Barnes in 1973 of successful treatment with the oral administration of zinc sulfate, the clinical response to this treatment has been confirmed by different investigators in many countries. In Korean literature, Rhim et al reported two cases of A,E. in siblings successfully treated with oral zinc sulfate in 1980. In our case of cow's milk-fed, 7 month-old male infant, typical claasical features of total alopecia, diarrhea and periorificial dermatitis developed at about 3 months. of age and the zinc level in serum was 101 ug/dl at the first visit. Treatment first with diiodohydroxyquin was initiated at a dose of 315 mg/day by mouth for the first week and 630 mg/day for the second week, but this therapeutic regimen brought about little or no effect. Because of no definite improvement even with increasing dose of 1260 mg/day for another week, treatment was. changed to oral zinc sulfate. The patient began to receive zinc sulfate 50mg at first day by mouth and the dosage was immediately increased to l00mg daily from the next day. Within 72 hrs there found dramatic improvement in the skin lesions and diharrhea stopped. Twenty days after the start of zinc therapy, nearly all the skin lesions disappeared and the patient was discharged in satisfactory condition with only mild residual erythema. (countinued..)
